Be it known that I, CHARLES W. SriNn, a citizen of the United States, residing at Cleveland, in the .county of Cuyahoga and Sta-te of Ohio, have invented certain new and useful Improvements in Gaseous-Fuel Burners, of which the following is a specification.

This invention relates to an improvement in gaseous-fuel burners, and the object of the invention is to provide a burner'of multitubular formation adapted to be produced in a simple and inexpensive way and which will operate eliiciently and be durable and lasting in use, and positively prevent back lirino.

Piimarily, this burner is .intended for stoves, ovens and furnacesusedl for domestic purposes, but the invention is .not necessarily restricted Ito such appliances. .However, as the requirements are exacting in burners used for domestic purposes the purpose is to fulfil such requirements with a burner which is adapted to use heavy hydrocarbon oils, scaling for instance from Baume 27 upward. The burner is also constructed in a particular way so that the gaseousfuel in passing through the burner is divided into a multitude of long line parallel streams flowing closely adjacent to each other, and so 'that a small bead or globe of green flame exists constantly at the immediate discharge end or mouth of each passage iwhile above these beads a vari-colored conical column of flame of considerable length is produced n which all the by-products of combustion are consumed. In other words, each small passage gives separate ignition at its head of al part of the escaping vapors, and the remainder immediately combines over the comb of passages to form a solid elongated column of flame tapering to a point, whereby all the vapor and by-products of combustion are consumed. Further, the multitude of long small parallel passages absolutely prevent back-firing under all pressures and mixtures, and the flame will not blow or lift oli' the seat of the burner under,

high pressures.

3 cast integral with the walls at the baseof the enlarged chamber within the head of the bowl` and the lower portion of this bowl member is-considerably reduced in diameter and connected with the enlarged portion by Haring walls vThe lower reduced extremity 5 is also preferably screw-threaded externally' so that convenient attachment and detachment may made with a header -or supply pipe 6 for the gaseous fuel. An-

nular wrench engaging faces 7 are also provided on the neck portion of this bowl member to facilitate its attachment and removal from the header or pipe 6. Preferably this bowl member is circular in cross section. but y it might-be square, hexagonal. of elongated form. or of other shape in cross section.'

'T he upper .chamber of bowl 2 and above grid 3 is also preferably circular or of the same shape or outline of the bowl. and a removable plug or core member 8 is snugly seated upon grid 3 within and enga-ged with the walls of the bowl. As shown this plug or comre member comprises an endless metal band or ring 9 within which a stripv of corrugated thin sheet metalv 10 and a plain flat strip ll of thin sheet metal are tightly coiled in facial contact to provide a multitubular body through which a multitude of fine attenuated streams of gaseous Huid is adapted to pass upwardly and issue separately at the top of the. burner bowl over the entire area. within' the confining walls thereof.

lin constructing the burner. a tlat'strip of thin metal of the proper width and length, say lof an inch, is passed between the corrugated rolls to produce alternate ribs and grooves on opposite sides of the strip and a strip so formed of relatively thin gage having ribs approximately one-eighth of an inch apart have been found to give very satisfactory results. One end of the plain i flat strip, 11 is first curled intov a small round roll12 and then the corrugated strip is placedon the flat strip and the two strips Wound spirally and tightly into as many folds as may be required to the proper diameter to completely lill ring' 9 whenf 'placed therein, substantially aS-shown in iig. 3. This plug member is then introduced in the bowl and the burner is-ready for use.

i burner constructed according to my invention creates a volume of iiame capable of consuming all the byproducts of com` bustion even though heavy oils 'are used, from which'the vapor is derived. There is no back-firing notwithstanding that the ag` gregate ofi'open areas at the burner surface 1s extenslve and large; there 1s also anl absence of back-pressure such as a Wire gauze often' crea-tes where introduced in the vaporv passage to prevent back-liring; the strip used being'of brass or non-corrodible metal, no change takes place in the size of the minute passages and as such passages are kept clean and free from corrosive deposits the burner has a long life; the Walls between the adjacent passages being relatively thin.

v outlet for a a minimum burner. t

In a square or rectangular burner the opening or bowl of the corrugated strip gaseous fluid in a medium size might be folded back and forth in parallel 40 layers, or a series of concentric corrugated layers might be sleeved together, but a spiral formation is preferred for th, lreason thatvery. tight folds can be quickly and `conveniently made in and to any desired 45 diameter. vA burner of approximately one and three-fourths inch in diameter embody-l ing this invention produces a high round conical flame of intenseheating character,

and this burner has been found to give e111-A 50 tire satisfaction in domestic ranges.

What I claim is:

l. 'A burner body having a relatively thin removable band seated therein Within which a cellular comb provides a multitude'of 55 vapor discharge passages co-axially ofthe ring.

2. A cylindrical burner body having a reduced extremity, a flaring fuel supply neck connecting said body-and extremity, and a 6o relatively thin removable' band therein within said body having a corrugated sheet-r metal strip compactly coiled therein.
